Dynamics of Interactions between Cerebral Networks Derived from fMRI Data and Motor Rehabilitation during Stokes

Bull Exp Biol Med. 2019 Jan;166(3):399-403. doi: 10.1007/s10517-019-04359-6. Epub 2019 Jan 9.

Abstract

The connections between large neuronal networks were analyzed in 12 patients with ischemic or hemorrhagic strokes and hemiparesis included in the course of the interactive brain stimulation in the area of the primary motor cortex by the analysis of independent components of fMRI. The results obtained in 3 patients are presented. Desynchronization of the visual networks with each other and with the motor networks as well as positive dynamics in Rankin scale and box and blocks test were observed in the patients. These data attest to a decrease in the importance of visual control during movements and probably on partial restoration of prioperception. The important role of interactive brain stimulation and network analysis of fMRI data in neurology are discussed.

Keywords: cerebral networks; disability; functional connections; hemiparesis; stroke.
